2 Claims.

This invention relates to hypodermic syringes for use in injectingvarious potions into a patient by the medical profession. Moreparticularly, the invention deals with providing a syringe with meansfor directly filling the syringe vial so as to expedite the time factorin administering a hypodermic injection. The novel features of theinvention will be best understood from the following description, whentaken together with the accompanying drawing, in which certainembodiments of the invention are disclosed and, in which, the separateparts are designated by suitable reference characters in each of theviews and, in which:

Fig. 1 is a side view of a syringe diagrammatically indicating themethod of its use; and

Fig. 2 is an enlarged sectional detail View of one end of a syringeindicating in part a hypodermic needle coupled therewith.

In the use of hypodermic syringes, a problem exists, particularly in thehandling of heavy oily potions that are injected into the patient byphysicians. In such instances, physicians have found the need to firstuse one needle for transferring the potion from a vial into the syringe,to then remove this needle and attach a hypodermic needle suitable forinjection. These operations are time taking and also require the use ofunnecessary equipment and to dispense with this I have provided a verysimple means in the form of a needle attachment to the syringe body, bymeans of which the potion can be directly drawn into the syringe, afterwhich the usual injection needle is attached to the syringe, preparatoryto the use thereof, thus eliminating one complete operation and the needfor handling and sterilizing of additional equipment.

In the accompanying drawing, I have shown at Ill the outline of asyringe, preferably of the "Luer Lock type. The syringe is provided, atone end, with a standard quick thread coupling H, with which a standardtype of syringe needle [2 is detachably coupled through interengagingcoupling portions ll, l2, as diagrammatically seen in Fig. 2 of thedrawing. Within the coupling II is a reduced tubular portion l3, throughthe bore M of which the solution is normally drawn into the syringethrough a suitable needle, which would be equivalent to the needle l2,except for the size of the stem portion of the needle. The needle [2 hassuch stem portion, as seen at I5.

To overcome the objections previously outlined, I mount in the bore 14,to extend beyond the tube [3 into the chamber portion of the needle I2 astub needle I! having a bevelled end 18 to form an elongated admissionopening l9 which is indicated in Fig. l'of the drawing. The stub needleII is utilized for passage through the usual rubber sealed end of a vial20, indicated in Fig. 1 for removal of a portion of the contents of saidvial, which operation will be 2 apparent from a consideration of Fig. 1;thereafter, the needle 12 is directly coupled with the coupling II, inthe manner illustrated in Fig. 2 and the syring is now ready for use toad-- minister the injection into the patient.

It will be apparent that the syringe is sterilized preparatory to theintroduction of the solution thereinto in the manner referred to in Fig.1 and the needle i2 will also be sterilized prior to its attachment tothe syringe.

With my improved construction and, simply by including the stub needlell, I provide means for directly filling the syringe, thus dispensingwith the use of the filling needle which is commonly employed.

It will be understood that the addition of the stub needle ll which canbe welded or brazed into position adds little to the initial cost ofproducing the syringe iii and, yet, adds materially to the practical useof devices of this kind.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In hypodermic syringes of the character described, a threadedcoupling at one end of the syringe with which a hypodermic needle isadapted to be detachably coupled, a tubular portion within and spacedfrom said coupling and a stub tubular needle arranged in and fixed tosaid tubular portion, and said stub needle having outwardly of saidtubular portion a long tapered outer end portion.

2. In hypodermic syringes having a threaded needle coupling at one end,a hypodermic needle adapted to be detachably coupled with said coupling,the syringe having, within and spaced from the coupling, a projectingtubular portion, the hypodermic needle having a chamber for receivingthe tubular portion of the syringe, the chamber extending beyond thetubular portion of the syringe, a stub tubular needle projectin beyondthe tubular portion and extending into said chamber when the hypodermicneedle is coupled with said syringe, and said stub needle having atapered outer end.
